Hi @leopold ,
Unfortunately, Power Automate doesn't currently have a built-in connector for directly posting to Facebook Groups due to Facebook's API limitations. However, there are a couple of workarounds you can explore to achieve your goal:
1.Schedule with Trigger: Set up a trigger in Power Automate Desktop to run the flow automatically. This trigger could be based on a schedule (every two weeks) or when a new file containing the updated link is detected.
2.Power Automate Desktop: This free tool allows automating desktop tasks. You can record yourself logging into Facebook, navigating to each group, and pasting the link.
(Note:- if you got your solution you can mark as solution and gives kudos)
Thanks & Regards
